I've now tested the device on two other systems with older releases; the
results seem to point to a regression somewhere between v3.2 and v3.8:
FAILS: linux 3.8.0-35-generic, bluez 4.101-0ubuntu8b1 (same
failure mode as Linux v4.2)
WORKS: linux 3.2.0-30-generic-pae, bluez 4.98-2ubu
Another log, this time capturing the module, function, line-number and
message.

Extract from the kern.log:

There are 2 functions that print the message "end: err %d":

I believe I've identified the root-cause:
$ hciconfig hci1 features
hci1: Type: BR/EDR Bus: USB
BD Address: 00:10:7A:4D:15:33 ACL MTU: 672:8 SCO MTU: 255:255
Features: 0xff 0xfb 0x01 0x00 0x00 0x00 0x00 0x00
<3-slot packets> <5-slot packets>
This looks to be a kernel issue in
net/bluetooth/mgmt.c::read_index_list(). rp->num_controllers, etc., is
set as hci_dev_list is iterated over. Some devices are not added due to
test flags or quirk bits.
I'll check how 'hcitool dev' gathers its list of adapters.
** Changed in: bluez (Ubuntu)
I've been working on this some more. I noticed that even when both
adapters are connected before bluetoothd starts, it does not find the
2nd adapter.
The problem appears to be in the read_index_list_complete() call-back,
which sees only 1 controller despite the RFkill events reporting 3
devices, 2
